Security Findings2

Severity	Finding	Layer	Location
MEDIUM	Excessive Tool Permissions via Generic Rube Execution The skill describes the use of generic Rube MCP tools (`RUBE_MULTI_EXECUTE_TOOL`, `RUBE_REMOTE_WORKBENCH`) for executing operations. While the skill's stated purpose is 'Lessonspace Automation', these underlying Rube tools are generic execution mechanisms. If an agent's reasoning is compromised (e.g., via prompt injection), it could potentially use these tools to execute any function available through the Rube MCP, not just Lessonspace-specific operations, leading to broader permissions than intended for this skill. Implement strict access controls or agent-side guardrails to ensure that `RUBE_MULTI_EXECUTE_TOOL` and `RUBE_REMOTE_WORKBENCH` are only used to execute Lessonspace-specific tools when operating within the context of this skill. If possible, configure the Rube MCP to limit the scope of tools accessible to this skill's integration.	LLM	SKILL.md:49
